Brazil unfurled a vast canvas celebrating its rainforest and the creative energy of their wildly diverse population to the tune of samba, bossa nova and funk in welcoming the world on Friday to the Olympic Games in Rio de Janeiro. Home to the Amazon, the world's largest forest, Brazil used the ceremony to call on the 3 billion people watching the opening of the world's premiere sporting event to take care of the planet, plant seeds and reconquer the verdant land that Europeans found here five centuries ago.
